G840 – Diphtheria, Tetanus, and acellular Pertussis vaccine/ Inactivated Poliovirus vaccine (DTaP-IPV) - paediatric
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service is for the administration of the Diphtheria, Tetanus, and acellular Pertussis vaccine/Inactivated Poliovirus vaccine (DTaP-IPV) to paediatric patients. It is marked with a '+' symbol, indicating it is an add-on procedure. According to the notes on page of the Schedule, if the immunization is the sole reason for the visit, G700 should be added. This service is listed as a delegatable procedure on page (), meaning it can be performed by a physician's employee under the conditions specified on page (). The immunization service may not be insured under some conditions as per regulations referenced in Appendix A of the Schedule.
When to Use
- Use G840 when administering the DTaP-IPV vaccine to a paediatric patient as a standalone procedure, ensuring G700 is billed alongside it to capture the visit fee.
- Use G840 in conjunction with a counselling service on the same day, as this is a specific exception to the general rule prohibiting multiple services on the same day.
Common Pitfalls
- Billing G700 when an assessment or consultation code is also billed for the same patient on the same day, which will result in an automatic rejection of the G700 premium.
- Attempting to bill G840 for adult patients, as the code is strictly restricted to paediatric populations and will be rejected for patients outside the defined age range.
- Failing to recognize that G840 is a delegatable procedure; billing it as a physician-performed service when it was administered by a nurse or employee is a missed opportunity for efficient practice management.
Billing Tips
- Always append G700 to G840 when the immunization is the sole reason for the visit to ensure you are compensated for the office visit component of the procedure.
- Verify that the patient is not enrolled in a capitation model that requires a 15% adjustment for G700, as this is a common source of payment discrepancies.
